This invention relates to mechanism for winding a thread or other covering strand about a core to cover the core.

Machines for winding a cover helically upon a core of elastic or inelastic fllament such as rubber, wire or textile thread have been extensively used heretofore. These winding or covering machines are commonly provided'with a hollow spindle through which the core to be covered may pass, and mounted upon the spindle to be rotated thereby is a spool' oripackage containing the thread or other form of covering material that is to be wound helically upon the core as the latter is advanced through the rotating a spindle.

It is important to provide a thread guide that will guide the covering thread and control its tension as this thread is unwoundfrom its source of supply upon the rotating spindle and wound about the core.v and travelers have been used heretofore for this purpose. n

The winding spindle is usually driven at very high speed. to speed up the core covering operation, and when a traveler ring is employed that x is supported in a fixed position while the spindle rotates, the traveler is pulled'rapidly around the ring by the covering thread. This subjects the traveler to severe wear and necessitates its frequent renewal. t

To reduce this wear it has been proposed heretofore, as disclosed in the Shorrock Patent No. `1,958375 to provide a cap adapted to be rotated by the package supporting spindle and removably mounted upon the upper end of this spindle, and the cap is provided with one or more traveler rings and travelers which may rotate with the ring and slide thereupon. It is found, however,`

that due to the very high speed at which the spindle is` rotated the mounting of the cap at the upper end thereof tends to increase its vibrawill be further understood from, the following description when read in connection with the Bothfiiers and traveler rings 19'36, Serial No. 76,730

accompanying drawing which illustrates good practical forms thereof.

In the drawing:

Figure 1 is a side elevation of core covering mechanism employing the construction of the present invention;

Figure 2 on a larger scale is a Vertical sectional view through the adapterof Fig. 1;

Figure 3 is a bottom plan'view of Fig. 2; and

Figure 4 is a side view illustrating a different application of the invention.

Referring to the drawing, 'Il is an electric motor the rotor 'l of which is mounted upon and drives the hollow spindle '2. This spindle projects from the motor a suicient distance to receive a spool or other form ofpackage contain ing the core covering thread. The core C which may be any filament to be covered, such as a rubber or tex-tile thread or a strand of wire, is passed up'wardly through the hollow spindle '2 by means .not shown but well known inthe art.

The'core covering material T may be a thread or narrow strip of any suitable textile material or other filament. The thread T is showndn Fig. 1 as wound upon a tube '3 which may be 25 formed of pasteboard, and this tube is mounted upon what is known as an "adapter" which is so constructed that the tube '3 can be easily mounted thereupon and removed therefrom.

The adapter shown comprises a barrel I 4 and a head "5 secured to .one end of the barrel, and extending lengthwise of the barrel are provided *three wires l adapted to center the tube '3 upon the barrel and frictionally hold the tube in place thereupon. The barrel has a notch "l at its lower end adapted to receive a driving key '8 on the spindle '2. After the tube '3 of covering thread is slipped upon the barrel H, the adapter may be placed upon the hollow spindle '2 to be rotated thereby. 4

The mechanism so far described was known heretofore, and in accordance with the present invention a traveler ring '9 is secured to the adapter head '5` to rotate therewith. This constitutes an extremely simple and practical means of rotating the traveler ring, and supports it' adjacent the adapter head where it is needed to guide the thread T about the head and to the point at which it is wound helically about the core C.

Various means may beemployed for supporting the traveler ring '9 upon the head '5 and this is accomplished in the construction shown by providing the ring '9 with a circular flange 20 which fits in a recess at the inner face of the head '5 and the flange is secured to the head by the screws 2'. The ring '9 may be provided with the usual traveler 22 through which the thread T slides as it is unwound from the supply packthe traveler ring '9.

The present construction not only provides a. simple and practical way of rotating the traveler ring to thereby lessen the relative travel between the ring and traveler, but by mounting the ring upon the adapter head the ring and adapter are dofi'ed together in replenishing the supply of thread upon the tube '3, which is a saving of time. Furthermore, since the adapter and ring rotate as a single unit a smooth steady guide for thethread T is provided.

Having thus described my invention what I ,claim and desire to protect by Letters Patent is:

1. A winder comprising a hollow spindle through which a filamentmay pass, means for rotating said spindle, a package support mounted upon said spindle to rotate therewith and provided with a head at one end, a traveler ring secured to said head to be supported thereby and to rotate therewith, and a traveler slidably mounted upon said ring.

2. A winder comprising a hollow spindle through which a filament may pass, means for rotating said spindle. a package support mounted upon said spindle to rotate there'with and provided with a 'head, a traveler ring secured to said head to be supported thereby and to rotate therewith, and a traveler slidably mounted upon said ring and adapted to guide a thread from a package uponsaid support about said head and wind it around said filament.

3. A winder comprising a hollow spindle through which a filament may pass, means for rotating said spindle, an adapter for supporting a yarn package mounted upon said spindle to rotate therewith and provided with a head at one end. a traveler ring secured to said head to be supported thereby and to rotate therewith, and a traveler slidably mounted upon said ring.

4. As an article of manufacture an adapter having a hollow barrel adapted to receive a thread package and a head upon one end of said barrel, a traveler ring secured to said head to be supported thereby, and a traveler slidable upon said ring.

5. As an article of manufacture an adapter having a hollow barrel adapted to receive a thread package and a head upon one end of said barrel, a traveler ring provided Jith a circular fiange for rigidly attaching the ring to said head, and a traveler slidable upon said ring.

6. As an article of manufacture a thread package support having a head, a traveler ring rigidly secured to said head, and a traveler upon said ring.
